☆ Analog resistance output |
• Higher measurement accuracy with the four-wire wiring method. • Self-calibration. |
☆ Multiple output methods |
• The instrument has a "fixed point output" mode, through the digital button of the Keypad or click the touch screen, directly set the required output value, the instrument will automatically switch to the best range output. |
☆ Multiple output methods |
• When calibrating a resistance tester, it is usually necessary to select the calibration point according to the proportion of each range of the meter to be checked. • The user can easily select the calibration point of the inspected meter through the "Percentage Output Button" on the console of this instrument or the "Percentage Check Point" on the touch screen. |
• The operating area is equipped with a "rotary encoder" that increases or decreases the output by rotating it clockwise or counterclockwise. |
☆ Statistical analysis of test data | ||
S/N | Function | |
Integration period: The integration period can be set in the range of 0.5 s ~ 20 s (default 1 s), which is convenient for users to set sampling data according to actual needs; | ||
